Megan M. has a high-profile job where appearance counts. She has looked in the mirror the past few days wondering what people are going to think.

“I have no doubt,” she said, “that I’m going to lose my hair.”

Before every woman hugs their hair in sympathy, it’s not what you think. At least not quite.

Megan is not undergoing cancer treatment, but Indianapolis coach Chuck Pagano is. So are too many other people. The baldness caused by chemotherapy makes them easy to spot. If everything goes as planned, Megan will join them Sunday.

You think Andrew Luck will be under pressure against the Bills? More than 62,000 people will see Megan get her head shaved by a guy dressed as a blue horse.

She’s sacrificing her brunette locks to raise money for cancer research. Megan is certainly not the first person to shave in solidarity. Plenty of people have done it for friends and relatives. About 30 Colts did it for Pagano.

But they overwhelming have one thing in common—they’re guys.

Megan will never be mistaken for a guy. She’s an NFL cheerleader. According to the Elias Sports Bureau, the league has never had a cheerleader with less hair than Vince Lombardi.

Now along comes Megan. Colts’ policy prevents us from using her last name. We can tell you she’s a small-town girl from Auburn, Ind., and her day job is in the health-care field.

This is her third year cheering for the Colts, whose season has turned into a cause. Everybody is rooting for Pagano.

Pagano, 52, was diagnosed with leukemia in late September and is on a leave of absence. His surprise appearance and speech in the locker room after the Miami game sent Kleenex sales skyrocketing nationwide.

As part of the Chuckstrong campaign, Indy’s mascot tweeted a challenge. If he could raise $10,000 in pledges by Sunday, would a cheerleader let him shave her head?

Megan thought about it for about two seconds, which is how long it took to recall the faces of a couple of friends who’d died of cancer.

She quickly called her boss to see if company policy required hair on women. It didn’t. Then she called her boyfriend.

“Megan,” he said, “you’re never going to be able raise $10,000 by yourself.”

“It’s kind of strange. I haven’t really had any second thoughts,” she said. “It’s just my hair.”

Just hair?

Maybe if you’re a guy not named Donald Trump. For every Hair Club for Men member, there are a dozen guys who proudly look like cue balls.

Think of all the famous bald men. Any list that includes George Washington and Homer Simpson is wildly extensive.

Now name some bald women.

Britney Spears was nuts, so she doesn’t count. A few actresses have shaved their heads for movie roles. But other than Sinead O’Connor or a teenager going through some awkward phase, females rarely take it all off and leave it that way.

“Hair is so true to what women are,” Megan said. “It’s part of the beauty of women. When people lose that, they lose part of what they are.”

One study showed that average woman spends $50,000 in her lifetime on hair. That’s a yearly average of $520 for cuts, $280 for products and $330 for coloring.

You can probably triple that for NFL cheerleaders.

“Hair is an integral part of the performance,” Megan said.

The term is “hairography.” It’s defined in the Urban Dictionary as “Choreography using a lot of dance movement with the head that causes the hair to thrash about.”

Most men would sprain their comb-overs if they tried it. But when done right by a bunch of professional-quality cheerleaders, hairography is a visual symphony. Now the Colts will have one bald note just trying to keep in sync.

“Do you flip the hair right or left with this dance move?” Megan pondered. “It’s part of the profession.”

That profession gets a shallow rap. Megan’s move might help dispel the notion that cheerleaders are just a jiggling collection of blondes, brunettes and redheads.

No doubt, their appeal is based on appearance. But if an NFL cheerleader can do without a major beauty component, it might help a little girl who’s fighting cancer realize life goes on.

“You may not have hair,” Megan said. “But you’re still beautiful.”

She hasn’t asked how much money has been pledged, but Megan has already planned to take her shiny head to visit children’s hospitals. You can help the cause on the Colts' website.

The game plan is for a stylist to cut Megan’s ponytail after halftime. Then Blue, the Colts mascot, will shave off all her hair.

“It’s going to grow back,” Megan said.

Until it does, she’ll look in the mirror each morning but shouldn’t worry what people think.

When they look to the Colts’ sideline, they’ll see how beautiful bald can really be.
